Make sure you use a servo choke too

Have tried doing this myself today but now the servo does not work. Is a KO 2123fet. Have i done something wrong?

Ive got the same servo, the blue fet lead should have a metal pin thing at the end, just push that into the + wire that goes to your lipo/cells
If it doesnt, just solder it onto the + wire.. if that doesnt work, the servo might be faulty
